      Space images show UK sweltering
      Sensors in space have recorded the dramatic increases in land
      temperatures and air pollution as the UK swelters in record-breaking
      July heat.
      The images show major cities like London, Birmingham and Liverpool
      experiencing the highest levels of the air pollutant nitrogen dioxide
      (NO2).

      Wisley in Surrey recorded an unprecedented 36.5C (97.3F) on 19 July.

      The images were generated from data gathered by the European Space
      Agency's Envisat and Nasa's Aura satellites.

      John Remedios, head of Earth Observation Science at the University of
      Leicester, said: "The latest satellite data shows a perspective of
      the environment in which we live that can only be obtained from
      space.

      "The images show temperature increases and increased pollution for
      every region in the UK."

      Dr Remedios added: "It is particularly striking to see the extent of
      temperature and pollution increases in the large cities, which have
      such a detrimental effect on the quality of life in those locations."


      Current climate change predictions for the UK suggest that the
      frequency of the these extreme periods of high temperature and
      pollution will increase
      Dr Gary Corlett, University of Leicester

      The images show the stark differences in land temperatures and
      nitrogen dioxide between 15 and 18 July when most of the UK
      experienced heatwave conditions.

      This period also coincided with the government issuing its second
      heatwave smog warning of the summer, when air pollution was
      classified as "high" or "very high".

      Future forecast?

      Researchers at the University of Leicester, who released the images,
      said the data could offer some insight into the future.

      "These extremes of temperature and of pollution are likely to occur
      periodically throughout this summer as the prevailing heatwave
      conditions maintain themselves," Earth Observation Science's Dr Gary
      Corlett said.

      "Moreover, current climate change predictions for the UK suggest that
      the frequency of the these extreme periods of high temperature and
      pollution will increase."

      The land temperatures were recorded by the Advanced Along Track
      Scanning Radiometer (AATSR), an instrument funded by the UK's
      Department for Environment, Food and Rural Affairs, on the European
      Space Agency's Envisat platform.

      The NO2 readings were taken by the Ozone Monitoring Instrument (OMI)
      onboard Nasa's Aura satellite.

      Scientists hope access to this sort of data will allow more accurate
      and quicker assessments of nations' compliance with air pollution
      limits.
